Hi Ron:
There is some clearance between a fully retracted piston and the pad. I
was able to push the pad away from the disk, and the against the the
rubber boots. I could feel the piston retract. But as soon as I release
them they snap back against the disks, propelled by the rubber. And I
can feel it the next time I step on the brakes, slightly longer pedal
the first time.

I measured some of the pads I have and the total thickness of
pad and backer is around .60".
I just measured a caliper with the pistons all the way in at 1.94" -
1.20 for the pads and .5" for the rotor = .024".
Your pads are .010" bigger than the distance in the caliper; if you have
an anti-squeal shim in the caliper it is even worst.
I would say that you need to thin those new pads to around .60" to have
some clearance.
